Fee models as published by the routes; gas on the source network is separate unless stated. Always verify the bridge domain — the four safety checks are in the bridge safety answer.
Bridging USDC only? CCTP burns and mints native USDC with no pool — about a dollar in gas, 30 seconds. Need the full Base entry walkthrough? Bridge-to-Base guide.
Frequently asked questions
How do crypto bridges calculate their fee?
Fast bridges charge a percentage of the amount (with a small minimum) because someone supplies destination liquidity immediately. The official bridge charges no protocol fee — you wait ~7 days and pay claim gas. The design differences are in the bridge safety answer.
When is the 7-day official bridge worth it?
Usually for amounts above $10–20k, where a 0.1% fee means $10–20. Below a few thousand dollars, fast routes cost pocket change and arrive in minutes.
Does this calculator use live bridge quotes?
It applies each route’s published fee model so you can compare expected costs. The exact quote drifts with liquidity — confirm on the bridge UI before signing.
